SOAP-GRANULATOR.

Application tiled January 30, 1904,

To all whom fit' may concern.'

in the borouglrof lflopatcong. in the county of Sussex and State of New Jersey, have inin Soap-(ranulatorsg and l do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

invention relates to soap dispensing devices, and more particularly to such a granulator comprising a screw fed follower for feeding the soap to a granulating device as particles are gradually detached from the cake of soap, and it has for its object to provide improved features of construction in the toothed spider for granulating the soap, also in the follower, and further in the coinbination of parts for attaining the advantages hereinafter specified.

For the accomplishment of the objects in view the invention consists in the features ot construction andin the combination of pa rts hereinafter particularly described and then sought to be clearly delined by the claims, reference being' had to the accompanying' drawing forming a part hereof, and in which- Figure 1 is a perspective of the granulator; Fig. 2 a longitudinal vertical section of the same; Fig. a transverse section; F ig. el an end view looking through the delivery end; Fig. a perspective of the follower and screw; and Fig. C a perspective of the parts of the spider before being assembled.

in the drawing the numeral 1 designates a cylinder or shell provided atone endwith a sleeve 2 swiveled thereto in a suitable manner, for instance by a bead 3 formed on the shell and fitting into a correspondinggroove -l in the sleeve, which bead and groove may be formed by stamping up a portion of the metal of both the shell and sleeve. and the raised or stamped up portion of the sleeve may be milled so as to forni a roughened surface to be grasped by the hand when the grannlator is manipulated to operate it. lVithin the sleeve 2 is formed what for convenience will be termed a spider which in the pres ent instance is formed of two V shaped metal Specification of Letters Patent.

plates (3 each of which is formed with notches or slits T so that the two may be brought together to form the spider 5 with a central angular opening or socket S. The outer ends E ot the spider arms are bent to form ianges vented certain new and useful Improvements or lips which will be soldered or braZed to the inside of the sleeve, and the inner edges of the arms will be serrated to form teeth' 10. the teeth of one arm being out of line with the teeth of another arm or staggered with reference to one another, said teeth serving to detach small particles of soap from the cake of soap within the shell when either the teeth or the cake of soap is turned, one in relation to the other. This affords a simple and strong spider with serrated arms constituting cutting blades for severing granulated particles of soap from the main body of the cake of soap.

lllithin the shell is a follower 11 threaded to a screw stem 12 and provided on its opposite faces, at its periphery, or next thereto, with studs 13 in alinement with each other. and the opposite ends of the screw threaded stem are made square or angular in cross section so that when the follower and stem are placed in the shell one of the square ends of the stem may tit in the angular socket S of the spider 5 carried by the swiveled sleeve Q. The outer face of the studs 13 are formed with a longitudinal groove 14 in which lits a key or longitudinally extending bead 15 formed in the wall of the shell 1 by stamping, or otherwise forming it therein.

rlhe end of the shell 1 opposite to the swiveled sleeve 2 is provided with a screw cap 16 which may be formed with a central. depression or recess 1T for one end of the threaded stem to t in.

lith the parts thus formed and assembled, and with a fake of soap 18 in the cylinder between the toothed arms of the spider and the follower and bearing against the former, if the shell be held fast and the swiveled sleeve turned, or if the latter be held fast and the former turned, or if both be turned in opposite directions, the teeth of the spider will detach small granular particles from the cake of soap which will be deposited on the hand held beneath the open end of the shell. At the same time the follower will be fed down by the screw threads of the stem so as to constantly press the cake of soap against the serrated blades of the spider. The follower cannot be turned inde- CII pendently of the shell because the two are held together against independent rotation by the key and seat connection between the two, and the cake of soap cannot turn independent of the follower because t-he stud 13 projecting from the face of the follower next to the cake fits in a corresponding recess formed in the cake of soap, and further by the longitudinal bead 15 of the shell l if the cake of soap be made with a corresponding groove to receive it, although the stud 13 entering a recess in the cake of soap may of itselfI be suflicient.

lllhen the follower 11 has reached the end of its travel and a fresh cake of soap is to be inserted in the shell, it is only necessary to remove the screw cap 1G and withdraw and invert the screw stem and follower thus bringing the follower to the upper or screw i cap end of the shell and inserting the inverted angular end of the screw stem in the socket of the spider' and causing the other projecting stud of the follower to enter the recess for it in the fresh cake of soap. It will thus be observed that by providing the studs 123 projecting from both faces of the follower and having both ends of the screw stein made angular, or alike, it is not necessary to run the follower from one end to the other of the screw stem when a fresh cake of soap is to be inserted in the shell, as by a mere inversion or transposition of the follower and stem the parts are brought into proper position. This saves time and Vlabor and simplifies the operation. A further advantage of having the studs project from opposite faces of the follower is that an extended surface contact is afforded between the studs and the bead on the inside of the cylinder and thus a better alinement of the parts is preserved; and an advantage of having the stud at the periphery of the follower is that it may enter a recess formed for it in the end of the cake of soap at its periphery and thus insure a secure locking of the cake of soap and follower together, and at the same time the stud will afford greater surface contact with the bead of the shell than would be afforded by merely the thickness of the follower'. It will be observed also that the thickness or diameter of the threaded stem is reduced for a distance near each end of the stem. This is for the purpose of freeing the follower from working engagement with the stem at such points so as to indicate by the non-feed of the soap that the cake of soap is practically exhausted or consumed and should be replaced by a fresh cake. This also prevents the follower or its projecting stud, from coming in contact with the teeth of the spider and thus damage to the teeth is prevented.

This granulator may be made of such diniensionsVV that it may be carried in the pocket or valise, and the open or spider end may be provided with a cap or cover 17 which may slip over the end and be held thereto by frictional contact.
